Abstract
Optic fibres provide independent static or rotating, single or multiple coloured light via optic fibres 1, which can be placed or distributed in any position inside aquariums or vivariums 7 to provide ornamental decoration or to enhance other internal objects. Light 3 is distributed to the optic fibres 1 via a light passage 4 offering a fixed or variable sequence of coloured light.
Description
2360832 USING OPTIC FIBRES IN A DISPLAY TANK The present invention relates
to the ornamental use of one or more optic fibres inside display tanks, and more particularly, the underwater use of optic fibres in aquariums.
optic fibres provide a single or multiple coloured source of independent static or moveable light decoration for particular application inside display tanks, such as fish tanks, aquariums or vivariums.
Presently coloured lighting and ornamental decorations for use in display tanks, such as aquariums, are widely available, but only in their separate forms. The currently available lights are normally placed inside an external canopy allowing light to penetrate display tanks from the top down. To date, this is the main application of light as a decorative feature in display tanks. For the purpose of electrical safety (where water or moisture is present inside display tanks), these light tubes or bulbs are located externally. The importance of electrical safety has also meant that no electrically powered ornaments are used in display tanks where water or moisture is present. For this reason, no internally placed light or singular ornamental decoration currently offers an independent source of illumination.
Optic fibres are place inside the display tank, uniting light and ornamental decoration.
Optic fibres will not cause electric short-circuiting or sparks. Optic fibres may be used in addition to or separately from the main external aquarium light. Optic fibres offer single or ever-changing coloured lights via optic fibres, which may be distributed 2-0 anywhere inside the display tank, providing a single decorative feature or the means te, enhance other static internally placed ornamental objects. Practical examples include the imitation of luminous marine and freshwater life forms (e.g. plankton) by placing optic fibres amongst the coral and rocks. Optic fibres may be placed in any location inside the display tank to enhance particular areas, such as rock caves and foliage.
2-15 When the main light is extinguished, the illuminating effect of optic fibres will 1 dramatically change the aquatic landscape. Optic fibres offer an attractive animated effect by using a fixed or variable sequence of colour lights to enhance static features inside the tank or may be used to imitate aquatic life such as luminous plankton. By using different diameters and numbers of optic fibres, light brightness can be increased or reduced to suit requirements. Single or multiple optic fibres of any diameter, shape or length may be used. Practical examples include the subtle illumination of aquariums containing nocturnal fish. This would enable the fislikeeper to view fish which normally hide away from bright fluorescent illumination. Optic fibres may also be used to illuminate shaded areas in the aquarium, for example rock caves, which are not t 0 normally illuminated by external canopy-located lights. This may allow fislikeepers to view the types of fish, which normally hide in such areas. The subtle illumination offered by optic fibres may also decrease the level of stress suffered by tropical and marine fish when bright external lights are turned on and off. Subdued lighting is also ideal when introducing new fish to the aquarium.
Aesthetically, optic fibres offer a more restful, subtle effect in the display tank, and illumination that can be localised to particular areas inside the aquarium. The subtle lighting offered by optic fibres may reduce the growth of algea inside the aquarium, which grows rapidly inside aquariums using fluorescent lamps. Optic fibres' high powered light source allows a significant reduction in the consumption of energy in 2-0 comparison with the fluorescent lamps currently used in aquariums, and the luminosity produced by the former is easily controlled by the simple replacement of one or more lamps. Optic fibres are appropriate to use in display tanks where heat transference must be avoided. Optic fibres do not fade or deteriorate in either marine or freshwater environments, and offer no source of pollution to the internal environment of display tanks, such as aquariums or vivariums.
Accordingly, this invention provides a light fitting comprising a holder for a high intensity light source, a reflector specifically adapted for use with a held source and juxtaposed wit h respect to the holder whereby a held source will provide a beam of a predetermined configuration, there being an orifice formed through the reflector and 3 o the light fitting including a fibre optic loom having an end coupler which is mounted to 2 cooperate with the orifice so that light from a held source will be incident on the end face of the coupler to enter the optical fibres of the loom, the orifice being formed through the reflector at a site where a majority of the light from a held source and impinging on that site does not contribute significantly to the resultant beam produced by the reflector.
An external light source reflecting on a single or multi-coloured static or rotating disk is positioned externally, offering a fixed or variable sequence of colours. The light source and the display tank are separated, thus permitting the application of various constructive compositions.
A specific embodiment of the invention will now be described by way of example with reference to the accompanying drawing in which: - Figure 1 shows in perspective the inventions' technical features; It will be immediately evident to one skilled in art that the above disciplined embodiment is merely exemplary of the present invention and various modifications and improvements may be carried out without departing from the scope of the invention.
Referring to the drawing (figure 1), shows one or more optic fibres or any diameter, shape or length 1, joined to an attachment coupling 2. An external light source 3 provides a single or multi-coloured static or rotating light. Light is diffused at the base 2-0 of the optic fibres via the orifice 4 through to the apertures in the attachment coupling 2. An external light source is housed in the external compartment 5. The base of the display tank will be of clear glass or any other transparent material 6. The display tank is shown as 7.
